6 Next: Local coordinate systems and the WCCS: Why and What + Concerns Diann Danielsen

7 Why a Local Coordinate System? Regional coordinate systems require ground-to-grid conversions to relate field surveyed coordinates to projected mapping coordinates Easy for staff to misapply or forget conversions Huge conversion effort for historic records Property maps have tens of thousands of ground-level distances on them. Too difficult to convert to map projections for GIS. Design drawings have tens of thousands of map projection distances on them. Too difficult to convert to ground distances for construction stakeout. Three Surfaces Earth s Surface Geoid Ellipsoid Distances on property maps and construction stakeout are measured here. Map Projection Surface GIS spatial databases and design drawings are developed here.

8 Wisconsin Local Coordinate Systems Old WisDOT county coordinate system used an average elevation and scale factor for each county to ease conversion between grid and ground values Typical project-based approach; does not preserve a precise mathematical relationship with other coordinate systems. Several Wisconsin counties began defining and adopting coordinate systems for local use WisDOT desired a unified set of county coordinate systems for the agency s large-scale mapping and roadway design activities that would be: Standardized and mathematically relatable to other systems Incorporate existing local county coordinate systems

9 Solution. Develop map projections that are even more localized than state plane coordinate projections No significant differences between ground distances and map projection distances Ground distances can be used directly in spatial databases and grid (design) distances can be used directly for stakeout.

10 Wisconsin County Coordinate System Fairview Industries was hired by WisDOT in 1993 to develop a consistent statewide set of county based coordinate systems This design raised the ellipsoid surface to near ground level to minimize ground and grid differences Local Map Projection Surface (Secant) Geoid Ellipsoid Enlarged Local Ellipsoid Surface Earth s Surface

11 Wisconsin County Coordinate System 59 separate map projections (Lambert and Transverse Mercator) 72 counties some share a projection

12 Use and Adoption of the WCCS Not officially adopted in statute (no current statutory home for coordinate system definition outside of a platting context) Chapter 236 updates were crafted to recognize and allow the use of WCCS for platting purposes WLIP & Task Force surveys indicate the WCCS has been adopted for use in ¾ s of Wisconsin counties

13 Use and Adoption of the WCCS WCCS has become a key component of the WLIP, recognized as a voluntary or de facto standard, and supported by a number of educational resources Statewide educational rollout in mid-1990 s Hardcopy and online resources

14 Emerging Issues Multiple county coordinate systems Jackson County Official Coordinate System (county adopted) Jackson County Coordinate System (WisDOT developed) Different naming conventions Badger County Coordinate System; Badger County Geodetic Grid; Badger County Coordinate Grid; WCCS Badger County; WCCS for Badger County; WCCS Badger Zone Questionable use of datums WCCS designed specifically for use with NAD83(1991) WisDOT plats being filed using WCCS Badger Zone; NAD83(1997) Variations create confusion when communicating and trying to convert data

15 Other Concerns Vendor Implementation Difficult because of the WCCS s unconventional design; mathematically correct, but less understood Vendor implementation methodology differs, resulting in different coordinate values for the same feature Lack of Formal Registration Some local systems adopted in ordinance; most are not Not registered with European Petroleum Survey Group/EPSG Aids consistent interpretation and implementation Lack of State Custodian/Oversight No designated entity responsible for Wisconsin coordinate systems or other spatial reference parameters (land and water datums, geoid models, ellipsoids, etc)

35 Two-Dimensional Rectangular Coordinate Systems Developable Surface and Projections A developable surface along with fit criteria becomes a projection that can be used to define a coordinate system. Three commonly used surfaces: Plane Cylinder Cone The developable surface is placed tangent or secant to the ellipsoid. Points are projected from the ellipsoid to the developable surface. The surface is rolled out flat without tearing the surface. Because a projection is mathematical, distortions introduced can be compensated for mathematically. Selecting the type, size, and orientation of the projection allows us to control maximum distortions.

58 WCCS: Emerging Issues & Solutions Al Vonderohe

59 Emerging Issue Enlarging the ellipsoid has the mathematical effect of modifying the underlying geodetic datum. This has caused difficulties in both the vendor and user communities. Vendors want to support WCCS, but there is complexity. Most of the user community doesn t have a clue about datums and map projections.

60 WLIA Task Force The WLIA Task Force on Wisconsin Coordinate Systems was formed early this year to address this and other issues associated with location referencing in Wisconsin. A question that emerged: Can the WCCS be re-designed so that: 1. There is no need to change the ellipsoid from GRS 80. That is, there will be one datum for all projections. 2. Coordinate differences between the existing and redesigned systems will be within negligible bounds. In this way, legacy databases and records will not have to be modified.

61 Leave the ellipsoid where it is and enlarge only the map projection surface. This way, the ellipsoid factor and the scale factor are nearly inverses of one another and their product = 1. Geoid Local Map Projection Surface Ellipsoid Map Projection Surface Earth s Surface

62 Approach to Lambert Re-Design Two strategies: 1. Make the original and re-designed map projection surfaces be identical in threedimensional space. This will cause the latitude of the central parallel (φ 0 ) to change. Challenge: Finding φ Hold φ 0 constant. This will cause the original and re-designed map projection surfaces to be dissimilar. Challenge: Finding k 0.

63 Approach to Strategy 1 Work in geocentric coordinates (3D rectangular). Use analytical geometry. Find equations of the line that is the projection of the central meridian. Find the point of tangency between GRS 80 ellipsoid and a line parallel with the above line. Convert X,Y,Z of this point to φ,λ,h. φ is the latitude of the central parallel.

64 Geocentric / Geodetic Coordinates Geocentric coordinates are based upon a 3D right-handed system with origin at ellipsoid center, XY plane is the equatorial plane, +X axis passes through λ = 08, +Y axis passes through λ = 908E. For any point, there are direct and inverse transformations between X,Y,Z and φ,λ,h. X Equator Greenwich Y P λ P Z φ P h P P Z P X P Y

65 Approach to Strategy 1 Profile through GRS80, enlarged ellipsoid, and original map projection surface at λ 0 : Map projection surface Parallel Geodetic coords = φ 1, λ 0, 0; Compute X,Y,Z Geodetic coords = φ 2, λ 0, 0; Compute X,Y,Z GRS 80 Find X,Y,Z of point of tangency. Transform to φ 0, λ 0, h. Enlarged ellipsoid Compute equations for this line. NOTE: Two sets of geodetic coordinates; one set of geocentric coordinates.

66 Approach to Strategy 1 To find k 0 : k 0 = R + D R Map projection surface where R is the radius in the meridian of GRS 80 at φ 0. D GRS 80 Enlarged ellipsoid Minor Axis R Ellipsoid Normal Compute perpendicular distance between these two lines.

67 Approach to Strategy 1 There will be discrepancies because the two ellipsoids do not have the same shape. Compute best fit translation in Y (change in false northing) and scale from sets of coordinates of points in both the original and re-designed systems. Points should be well-distributed across geographic extent. Apply these best fits to final re-designed parameters.

68 Dane County Test of Lambert Methodology (Strategy 1) X = m; Y = 0.000m X = m; Y = m X = m; Y = 0.000m X = m; Y = m X = m; Y = m

69 Approach to Transverse Mercator Re-Design Hold all parameters initially constant except k 0. Compute new k 0 in manner similar to that for Lambert re-design. Compute best fits for translation in Y (false northing) and scale. Apply best fits to final parameters. NOTE: Cannot hold map projection surface identical because the 2 cylinders have different shapes.

70 Lincoln County Test of Transverse Mercator Methodology X = m; Y = m X = m; Y = m

71 Conclusions Under the re-design, all WCCS would have a single, common datum based upon the GRS 80 ellipsoid. Initial tests indicate that WCCS can be redesigned to within 5mm or better. The WLIA Task Force has deemed 5mm to be a negligible difference. The WLIA Task Force is recommending redesign.
